Burt, Cincinnati, Charles L. Gunn, Springfield Township, Hamilton County, and Albert G. Sturdevant, Cincinnati, Ohio, assignors to The Procter & Gamble Company, Cincinnati, Ohio, a corporation of Ohio Filed Feb. 1, 1965, Ser. No. 429,556 7 Claims. (Cl. 22S-41) This invention relates to a package for a roll of continuous sheeting material. More particularly, the invention relates to a package of this class in which a roll of continuous sheeting material is suitably supported such that it is plainly visible before and during use. The invention also provides an improved form of dispensing package for a continuous sheeting product in roll form.

Dispensing packages of this general type are commonly found in which the roll of continuous sheeting material is completely enclosed. This, of course, makes it entirely impossible for a potential purchaser to see and inspect the product. It also has the detrimental effect of making i-t diiiicult, if not impossible, to visually determine the quantity of product remaining on the roll when in use. It is lalso typical ot prior packages of this kind to provide a cutting lblade having -a serrated cutting edge fastened to a wall of the package. However, the cutting blade is usually attached in such a manner that the user must handle the package with care in order to avoid cutting of his ngers.

It is a principal object of this invention to eliminate these deficiencies by providing an improved package which is rigidly constructed and yetdisplays the product. The package uses a relatively small amount of paperboard or like material thereby achieving a very economical construction.

Another object of the invention is the provision of a new yand improved package structure which is particularly suited for supporting continuous sheeting material in roll form, the structure of the package being such that it can be formed on high speed packaging machinery thus making the package commercially feasible.

Still another object of the invention is the provision of a package of this kind wherein large areas of the product are visible to a potential consumer thus allowing the distinctive and attractive appearance of the product to be inspected at the point of purchase.

A further object of the invention is the provision of a package of the character described which is convenient in use and which readily allows removal and cutting away of a desired length of the continuous sheeting material from the roll.

Yet another object of this invention is the provision of a package of this character which has a serrated cutting edge so located and joined to the package as to prevent accidentalcutting of the fingers by the user no matter how the package is manipulated in withdrawing the continuous sheeting product from the roll.

Another object of the invention is the provision of a package of the character described which is constructed to support a roll of continuous sheeting material wound on a core with provision to support the 'core ends securely in the package to allow tree rotation of the core without dislodgment from the package during use.

The nature and substance of the invention can be briefiy summarized as comprising a package for a wound supply roll of continuous sheeting material, said package being made from a blank of paperboard or like material which is cut, scored and folded into a frame blank having tubular supports on either side of its four wall-forming panels. An aperture is cut in the tubular supports located in the Fice end panels of the frame lblank structure. The apertures are configured to receive and support the ends of a cylindrical core having the continuous sheeting material Wound thereon. A cutting device is attached to one of the tubular support elements on one side wall, preferably so that its cutting edge faces inwardly toward the roll of continuous sheeting material thus protecting the fingers of the user. The frame blank is formed around the roll of continuous sheeting material by placing the extensions of the core at both ends of the roll into the apertures in the tubular supports at the end panels and thereafter joining the ends of the frame blank. The package is`preferably further completed by overwrapping the frame with a transparent plastic film, preferably one having heat-shrinkable properties. The overwrapped film is heated and shrunk to add substantially to the rigidity of the completed package. The roll of product within the package has a relatively large portion of its surface exposed through the two open sides of the frame so that it may be readily examined by a potential consumer. l

While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter regarded as forming the present invention, it is believed the invention will be better understood from the following description taken in connection with the accompanying drawings in which:

Reference will now be made to the drawings in describing the invention and the manner of making and using same. A frame blank 10 generally configured in the form of an elongated strip is illustrated in flat condition in FIGURE 1. The frame blank 10 is formed by cutting and scoring a suitable packaging material such as card-v board, paperboard, cartonboard, plastic, thin metal or the like. The frame blank 10 is divided successively into a Hap 11, an end panel 12, a side panel 13, an end panel 14, and a side panel 15 by means of'spaced horizontal paral- 3 lel score lines 16 and 17 and vertical parallel transverse score lines 18, 19, 20 and 21. The score lines 16 and 17 run longitudinally from one end of the elongated strip forming the frame blank to the other end thereof.

Extending portions 22, 23, 24 and 25 project laterally outwardly from the longitudinal score line 16. Similarly, extending portions 26, 27, 28 and 29 extend laterally outwardly from the longitudinal score line 17.

Each of the extending portions 22, 23, 24 and 25 are divided by means of the horizontal score lines 30 and 31 -into an inner area 32, an intermediate area 33 and an outer area 34. Similarly, the extending portions 26, 27, 28 and 29 are divided by means by the horizontal score lines 35 and 36 into an inner area 37, an intermediate area 38 and an outer area 39.

Angular relief cut-outs 40, 41 and 42 are provided between the extending portions 22, 23, 24 and 25. Similarly, angular relief cut-outs 43, 44 and 45 are provided between the extending portions 26, 27, 28 and 29. It will be noted that the angular relief cut-outs are formed by makinga straight cut co-extensive with one of the transverse score lines 19, or 21 while the adjoining cut is formed by cutting -a V-shaped notch extending from the horizontal longitudinal score line 16 or 17 to a point near the score lines 31 or 36 and then cutting straight out parallel to the adjoining straight cut to leave a narrow gap at the outside edge of the cut-out.

A cutting device is provided which may take the form of a blade 46 of plastic or metal having a cutting edge 47. The blade 46 can be secured to the blank on the outside surface of the inner area 37 of the extending portion 27.

' Preferably, the cutting edge 47 is serrated but other types of cutting edges will be satisfactory in practicing the invention. Other forms of cutting devices can also be substituted for the blade 46 such as forming a jagged edge on the frame blank material or providing a cutting edge made of a resinous material applied to the frame blank. The cutting blade 46 is mounted so that the cutting edge 47 extends slightly outwardly of the score line 35. The blade 46 can be mounted in various ways. One convenient way is illustrated wherein the blade has protrusions punched from its body which are forced through the material of the frame blank 10 and are folded over as shown at 48, 49, 50, 51, etc.

It will be noted that the extending portions 23, 25, 27 and 29 are provided with a series of spaced parallel cuts in their outer areas 34 and 39. For example, the extending portion 23 has spaced cuts 52, 53, 54 and 55 extending inwardly from the edge of the blank to the score line 31. Similar cuts are provided in .the extending portions 25, 27 and 29 as illustrated. These cuts are desirable and useful when folding and gluing the frame blank into shape as they give the outer areas 34 and 39 greater exibility thereby making them more readily folded and glued in place with little lapse of time when hot-melt adhesives are used for that purpose.

The extending portion 22 is provided with an aperture 56 formed by making a straight cut 57 and an arcuate cut 58. The straight cut 57 lies on the score. line 31 and the arcuate cut 58 lies in the intermediate area 33. A substantially identical aperture is cut from the extending portion 24. The apertures 60 and 61 correspond, respectively, to the apertures 56 and 59 as they are cut from the extending portions 26 and 28, respectively. In short, it will be noted that the extending portions 22, 23, 24 and are geometrically identical when folded over to the extending portions 26, 27, 28 and 29, respectively.

The flat frame blank 10 of FIGURE 1 is folded and formed into the structure shown in FIGURE 2 as the next step in the construction of the package. This is accomplished by folding the extending portions 22, 23, 24 and 25 on the score lines 16, 30 and 31 so that the outer area 34 on each of the extending portions lies in contiguous relationship with its respective panel 12, 13, 14 or 15. The extending portions 26, 27, 28 and 29 are similarly folded so that the outer area 39 on each of the extending portions is also contiguous to its respective panel 12, 13, 14, or 15. When so folded, the frame blank has a cross section as shown in FIGURE 3. The folded and formed frame blank is held in this relationship by the application of adhesive to the areas 62 and 63 (FIGURE 3) along the entire length of the blank.

It will be noted .that in folding the frame in the previously described manner, a tubular support 64 is formed along one edge of each of the side and end panels and a second tubular support 65 is similarly formed along the other edge of each of the side and end panels. These tubular supports are spaced apart and are relatively rigid by virtue of their geometric structure and because of the inherent rigidity of the material from which they are made. It will also be noted that the apertures 61 and 59 in the tubular supports 64 and 65, respectively, at the end panel 14 are in position to receive the projecting core of the supply roll.

Preferably, the tubular supports 64 and 64 are triangular in cross section as shown in FIGURE 3. This gives the frame and the package greater stability and rigidity. However, the frame blank can be cut, scored, and folded so the tubular supports 64 and 65 have other cross sectional shapes,-e.g., quadrilateral, arcuate, etc., to achieve similar results.

The folded and formed frame blank of FIGURE 2 isin condition for further folding to receive a roll of continuous sheeting material. This can be initiated by folding the structure into a conguration similar to that shown in FIGURE 4. Before the end tlap 11 is tucked in place, however, a supply roll 66 of continuous sheeting material wound on a core is mounted within the frame. The support for one end of the supply roll is best shown in FIG- URES 6 and 8. In referring to FIGURE 8, it will be noted that the supply roll 66 has continuous sheeting material 67 wound on a core 68, the end 69 of which projects beyond the edge 70 of the sheeting material 67. A similar projection of approximately equal length is provided at the other end of the core 68. The projection 69 is tted within the apertures 59 and 61 thereby supporting the roll 66 at one end. Similarly, the other projecting end of the core is fitted into the apertures 56 and 60 when the flap 11 is tucked in place to complete the frame around the roll 66.

After placing the supply roll 66 in the frame so that the core ends engage the apertures 56-60 and 59-61, .the flap 11 is tucked into the position illustrated by broken lines in FIGURE 9. It will be understood that the flap 11 iS tucked between the tubular supports 64 and 65 and the inner surface of lthe side panel 15. It will be noted in FIGURES 1 and 2 that the intermediate areas 33 and 38 on the extending portions 25 and 29, respectively, are cut away at 33a and 38a, respectively. Similarly, the outer areas 34 and 39 are cut short at 34a and 39a, respectively. Thus, the right end of the frame blank in FIGURE 2 provides suilicient clearance between the tubular supports 64 and 65 and the panel 15 to receive the flap 11 when tucked into the position of FIG- URE 9. The ap 1:1 is secured by means of'an appropriate adhesive. As an alternate construction, the flap `11 can be placed against the outside of the panel 15 and secured by means of an adhesive. It will also be apparent that the flap 11 can extend from either end of the frame blank of FIGURE 1 withoutdetracting from the advantages of the frame structure.

FIGURE 5 illustrates the corner structure of the frame. It will be noted that the angularly relief cut-outs in the frame -blank '10 provide a structure wherein the respective tubular supports on adjoining panels interlock and form a bevel corner. This provides a structure whereby the ends of the tubular supports 64 and 65 on one panel t within the ends of the tubular supports on the adjoining panel. Those of the tubular supports which -have squared ends .abut the inside surfaces of the adjoining panel. An example is illustrated in FIGURE 5 rwith respect to the corner between the side panel and the end panel 14. This type of structure provides added rigidity at the corners. It also insures a substantially square corner at each of the four corners of the package.

lFIGURE 9 illustrates the frame structure overwrapped with -a transparent plastic film material. The -iilm material is preferably of the heat-shrinkable type such as, for example, bi-axia'lly oriented polyvinyl chloride, polyethylene, polypropylene, or the like. It is also possible, of course, to use a non-shrinkable overwrap film such as cellophane, polypropylene, polystyrene, or the like. overwrap material is cut to size and then wrapped around the frame. It is sealed longitudinally along one side panel whereupon `the tucks 71 and 72 are made. The end folds 73 and 74 are then formed and sealed against the package. The other end of the package (not shown) has the ends of the wrapper similarly formed and sealed. When a preferred heat-shrinkable lm -is used, the finished package is then subjected to sufficient heat to cause the overwrap film to shrink thereby greatly increasing the rigidty of the frame structure. The use of a transparent overwrap film allows inspection of the supply roll 66 of continuous sheet material from the two sides of the open frame.

When a portion of the continuous sheeting material 67 is to be withdrawn and cut from the roll 66, Athe outer wrapper is first removed. Then, as shown in FIGURE 10, end 75 of the roll 66 is w-ithdrawn over the cutting blade 46 which is mounted on the tubular support 64. After a satisfactory length has been withdrawn, the user merely pulls down against the cutting edge 47 to sever a piece from the roll of continuous sheeting material.

In order to prepare for removal of the next portion, the roll 66 is turned so that the free end of the continuous sheeting material is exposed above the cutting blade 46. This is accomplished by merely grasping the roll 66 from the open sides of the package (arrows A and B in FIGURE 7) and turning the supply roll 66 in the frame until the free end of the continuous sheeting material is exposed.

By referring to FIGURE 7 it will also be noted that the cutting blade 46 is mounted on the tubular support 64 so that the cutting edge 47 faces inwardly. This provides a mounting for the cutting blade 46 which is particularly inaccessible to the hands of the user and greatly diminishes the possibility of accidental injury.

The package heretofore described is useful for supporting and dispensing any of several materials which are particularly adapted for commercial sale in roll form. For example, it can be used in the dispensing of continuous sheet material such as paper products including hand towels, wrapping paper, waxed paper and the like. It can also be used for dispensing plastic film products or metallic foil products. In one application, the in- Ventian was successfully used for displaying and dispensing a roll of detergent impregnated disposable paper dishcloths of the type described and claimed in U.S. Patent 3,121,249 issued to S. B. Aiileck et al., on February v18, 1964. In general, however, the invention is useful for dispensing any type of continuous sheet material in roll form as the foregoing specific examples are merely illustrative of a number of potential uses.

While particular embodiments of the invention have been illustrated and described, it will be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention and it is intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
